Kendrick Nunn scored 21 points and Illinois dominated in overtime Thursday to beat Michigan, 64-52.
The win was the fourth straight for the Illini (17-8, 7-5 Big Ten).
Illinois trailed the Wolverines (13-12, 6-7) much of the night but scored the final seven points of regulation and willed the game to overtime with tough defense.
From there Nunn scored four of Illinois' first six overtime points. The first two gave the Illini their first lead since the first half, 52-50. The second two all but put the game out of reach of the reeling Wolverines, 56-50.
Illinois closed the game on a 21-2 run.
Illinois guard Rayvonte Rice played for the first time since Jan. 3. He had been out with a broken hand and a suspension for a violation of team rules. He scored just 4 points but had a key steal to send the game to overtime.
Before the game, Illinois basketball coach John Groce announced Rice would return from suspension against Michigan, but guard Aaron Cosby will not.
Groce said he was pleased with Rice's progress but added he told Cosby to "take some time away from basketball."
Rice last played for Illinois on Jan. 3 against Ohio State. He broke his hand in practice the following week, but was suspended along with Cosby before the Jan. 31 game against Penn State for unspecified rules violations.
Without Rice Illinois has gone 6-3.
Rice is Illinois' leading scorer with 17.2 points a game.
